To prevent the latch from being forced out Fig. 7 is a vertical transverse section taken from the spring into engagement with the 75 2 5 in line '7 of Fig. 4, looking in the direction of stops, so that the clutch will only be thrown the arrow; and Fig. 8 is a front elevation of into engagement at the will of the operator,I the movable anvil and riveting-tools. pivot on the under side of the frame a bell- In making my improved glove-riveting inacrank lever H, provided with an upturned chine,I make a frame A, adapted to be loend 7L, which stands when in its normal po- 8c 3o cated upon a table, bench, or other suitable sition in the path of the latch.V The surface support and attached thereto in any convenof this lever as it approaches the upturned ient manner.

I mounta recipgradually operated upon and pressed back rocating armB in this frame, hung or pivoted into its groove in the clutch by an inclined on a shaft or pin C. The rear end of the removement, thus preventing any sudden jar eiprocatin g arm is provided with a pitnian D, or breakage that might occur were it not thus pivotally hung thereon by a pin d.

The bell-crank the front end of such arm. lever is held by a spring 7L in its normal po- Arranged on the shaft E, and preferably sition in the path of the latch, and when it is outside of the frame A,is a clutch F. This desired that the latch should be permitted to clutch is fixed to the shaft E by a spline or be forced out by the spring to engage with roo 5o otherwise, so as to rotate it when the clutch the stops G, so as to throw the parts into conis rotated. In the side of this clutch there is cussion, the operator can do this by means of the foot-lever 7b2. The instant this is done the latch is protruded, the concussion of the parts is effected, the shaft E rotated, and the various parts set into operation. The instant, however, that the foot-lever is released the spring h throws the bell-crank lever into its normal position, the latch is intercepted, thrown out of engagement with the stop g, the shaft E stopped in its rotation, and the other parts held stationary.

As it is desirable that the reciprocating up and down movements of the ends of the reciprocating arm B should always be interrupted or suspended at a point which willv leave the forward end of such lever inV its up position, the parts are so arranged that the latch will only be thrown out of engagement and the parts stopped at that point of the revolution of the shaft E as will leave the forward end of the reciprocating arm up.

To prevent the latch f from being forced Y. too far out of its groove or channel by the spring seated behind it, I have provided its inner end with an outwardly-proj ectin g point f, and have provided the inner face of the pulley G with an annular groove in which such projecting point may rest. This groove is of sufficient width to permit the latch to be pushed in or forced out, but serves to stop its outward movement at the predetermined f desired extent.

ciprocating arm.Y Plunger K is arranged inV such forward endY and immediately over the burr-set and extending down into it, as shown in Fig. 5. The spring-plate I is intended to be stiff enough to prevent the burr-set from yielding until it has sufficiently compressed the material to be riveted. The plunger K,

j however, is forced down the full extent of the movement of the forward end of the reciprocating arm, which of course is intended to be enough to upset the rivet. To enable the rivet to be adjusted in place and then brought 4or moved into its position under the burrset, where it may be struck and upset by the Y plunger, I arrange a movable anvil L in proper position at one side of the forward end of the reciprocating arm or in such convenient position as may be preferred. This anvil may be turned by the hand out'and in position under the plunger. It is preferably arranged to be slid in or out of its anvil-block L, which is pivoted to enable it to be turned in and out of position. This anvil-block may be supported on the frame A. with the reciprocatingarm and intermittingly-rotatable shaft. This enables the movable anvil to have different positions of its surface brought under the plunger, so that one or more rivets may be driven, as desired. This capacity to be slid in its anvil-block also permits the movable anvil to have dierent portions of its surface arranged fordifferent kinds of work, as illustrated in Fig. 1.

To secure accuracy and insure the exact posit-ion of the rivet under the plunger, the movable anvil is provided with stops Z, which limit the extent to which it can be slid. When slid so that one stop strikes the anvilblock, it will always be known that, when swung into operative position, a particular portion of its surface is immediately under the plunger and that the material containing the rivet placed on such spot will be properly struck by the plunger and the rivet upset. I have provided these movable anvils with numbers, although letters or other characters maybe employed, under the spot where the head of the rivet rests. NVhen struck by the plunger, the particular number, letter, or character on the movable anvil will thus be impressed into the head of the rivet. This enables me always to know what particular operator did any work that may be defectively or carelessly done, as of course it will be understood that the machines under the charge of dierent operators will be provided with different numbers, letters, or characters.

To prevent the movable anvil from being swung too far when moved into operative position, I arrange a lug IWI on the frame and a stud m on the anvil-block. I provide the lug with athreaded bolt-hole, through which a bolt is screwed the requisite distance to be struck by the stud exactly when the movable anvil is in the proper position under the plunger. By using a bolt, which may be screwed in or out, movable anvils of` different sizes and shapes may be employed, and yet always adjusted exactly to the position for the work.

To prevent the reciprocating arm when it becomes worn at its pivot-point from rocking or getting out of alignment orits proper position, I have provided a plate N at one side, which may always be adjusted by the set-screw n, so as to be held in close position against the side of the reciprocating arm. This will always insure constant and close contact between ,the reciprocating arm and its supports at each side and prevent wab` bling or lateral vibratory motion of the front end of the reciprocating arm, owing to wear or other cause. v

In order to adjust the movement of the plunger to adapt it to different kinds of work, I have provided it with screw-threads and the forward end of the reciprocating arm with a hole for it provided with corresponding threads. This will permit theV plunger to be adjusted up and down, as desired. To secure it from Vaccidentally becoming displaced or moving or changing position while in work, I prefer to arrange a lock or jam-nut above the reciprocating arm to hold it in the position to which it may be adjusted from time to time.
